VAPORIZER OR CARBURETER FOR GAS-ENGINES.

SPECIFICATION forming part of Letters Patent No. 792,670, dated June 20, 1905.

Application filed March 7, 1905. Serial No. 248,791.

To all whom it may concern:

Be it known that LCHARLns D. SHAIN,acitizen of the United States, and a resident .of Rockaway Park, in the county of Queens and State of New York, have invented a certain new and useful Vaporizer or Carburetor for Gas-Engines, of which the following is a specification.

My invention relates to improvements in Vaporizers 0r carbureters in which a valve or sprayer is used in connection with a means of adjustment; and the objects of my improvement are, first, to provide a ball valve or sprayer which is automatically operated; second, to afford facilities for regulating the lift of said :ball valve :or sprayer; third, to provide an automatically-operated intake for air; fourth, to provide means for controlling the amount of gasolene or liquid fuel entering the vaporizer or carbureter; fifth, to provide means for throttling or controlling the amount of gas, after same is formed, entering the cylinder of the engine; sixth, to provide means for controlling the amount of gasolene supplied to the vaporizer or carbureter in conjunction with the amount of gas entering the cylinder of the engine. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of the vaporizer or carbureter. Fig. 2isasection through the vertical section of Fig. 1 at X. Fig. 3 is a perspective view.

Similar letters refer to similar parts throughout the drawings.

In Fig. 1 the ball A in the mixing-chamber U forms part of the valve and acts as a sprayer. It is seated to one-half its diameter in the support B. The lift of the ball A is caused by the suction of the engine through the gas-outlet G and the pressure of the gasolene in the tube D.

The sliding rods E and E are connected at the top by a concave piece F, which fits the top of the ball A. The sliding rods E and E pass through holes in the supportB and then pass through a bottom piece G and are secured to the ring H. The thumb-nut I has a thread on the inside and is screwed up and down on the tubeD to permit an adjustment of the lift of the ball A caused by suction of the engine at the gas-outlet C and an adjustment of the lift of the ball A caused by the pressure of the gasolene in the tube D.

J is one of two semicircular shutters in the air-chamber K, one hinged on each side of the bottom piece G and raised or lowered automatically by the suction of the engine through the gas-outlet G.

The two halves of the vaporizer or carbureter are bolted together at Z Z.

L is a cock with a lever M connected to the tube D to control the amount of gasolene flowing through it. The lever M has a hole near its end m. (See Fig. 3.)

N, Fig. 1, is a hollow half-sphere pivoted at two sides O O and connected to the lever P, at one end of which is a stud R, (see Fig. 3,) to which is connected the rod S, with an eye fitting over the stud B. This rod passes through the hole on in the lever M. The rod S has two stops T and T, so that the levers P and M may be moved in conjunction, their relative movements being regulated by the placement of the stops T and T.

The pressure of gasolene, if suflicient, on the ball A, Fig. 1, through the tube D will cause the ball A to rotate and the gasolene will be sprayed around the surface of the ball A, materially assisting vaporization in the formation of gas.

This vaporizer or carburetor can be made in several ways; but I prefer to carry out this feature of my invention as shown in Fig. 1. It can be used either with or without a float V, Fig. 3, placed in the pipe-line y y between it and the gasolene-tank Y, this arrangement of the float V,-shown in the drawing Fig. 3, forming no part of my invention.

What I do claim as my invention, and desire to secure by Letters Patent, is

1. In a vaporizer or carbureter, a ball located in the mixing-chamber and a supporting-seat and a tube for gasolene or liquid fuel discharging under the ball; the lift of the ball being automatically caused both by suction of the engine and pressure of the gasolene in the tube under it, all substantially as set forth.

2. In a vaporizer, or carbureter, a ball located in the mixing-chamber and seated in a hinged to the bottom of the vaporizer or carbureter to automatically control bysuction from the engine, the quantity of' air taken into the air-chamber, all substantially as set 5 forth.

Witness my hand this 6th day of March, 1905, at the city of New York, in the county and State of New York.
